The buyer problem: tax work joins several kinds of evidence
A VAT or tax assignment may begin with a client workbook, but the answer often depends on invoice detail, reconciliations, registration information, accounting records and the relevant Nepal provision. Records can arrive late, totals may not reconcile and a schedule may contain manual adjustments that are not explained in the source documents. The team needs to see what a figure represents before it can investigate the treatment. A useful workflow keeps the workbook movement, invoice support, assumptions and legal research visible instead of reducing the work to a single calculated total.
